Topsheet for absorbent article

1. A topsheet for an absorbent article comprising a first fiber layer disposed on the side of a wearer and a second fiber layer disposed on the side of an absorbent member, said first fiber layer and said second fiber layer being partially bonded together at joints in a prescribed pattern, said first fiber layer having protrusions on the side of a wearer in portions other than the joints, and said second fiber layer being a fiber aggregate containing a heat shrinkable fiber and having heat shrunken parts that have shrunken and densified parts that have been inhibited from heat shrinkage, and wherein said densified parts are arranged at a smaller pitch than said joints.

2. The topsheet for an absorbent article according to claim 1 , wherein said densified parts are formed by heat embossing said fiber aggregate before heat shrinkage.

3. The topsheet for an absorbent article according to claim 1 , wherein said second fiber layer contains 30 to 100% by weight of a heat shrinkable fiber, and said first fiber layer contains 50 to 100% by weight of a fiber that does not shrink at the shrinkage starting temperature of the heat shrinkage fiber and further contains a heat shrinkable fiber in a proportion of from 0% by weight up to a percent by weight lower than the content of the heat shrinkable fiber of said second fiber layer.

4. The topsheet for an absorbent article according to claim 1 , wherein said first fiber layer has an apparent thickness t 1 of 0.1 to 3 mm, said second fiber layer has an apparent thickness t 2 of 0.2 to 1.5 mm, and the topsheet has a total basis weight of 20 to 80 g/m 2 .

5. The topsheet for an absorbent article according to claim 1 , wherein the topsheet has at least one densified part per protrusion.

6. The topsheet for an absorbent article according to claim 1 , wherein the heat shrinkable fiber is a self-crimping fiber.
